Excellent! The joystick calibration fix was especially needed and appreciated. It fixes joystick axes: before, SDL would report a max value for any movement on the axis until you moved and released the stick (apparently, max was whatever the greatest value in that direction the joystick had reported thus far, and that included the neutral position!) It now reports the correct absolute values.

Definitely a welcome change for devs that want to work closely with joysticks.
